    ObjectBuilder2

    ObjectBuilder2

    C++ CASE tool, full life cycle code generator

    ObjectBuilder is a C++ code generation CASE tool (CASE, code generation, refactoring, documentation generation). It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction. ObjectBuilder dramatically simplify work with C++ project architecture. I use it and think that tree OO interface targeted to C++ more fast and power than UML class diagrams. ObjectBuilder perfectly organize C++ header files with any level of complexity. Even if you use loop-references if OO hierarchy, you need include only one project-level header file. You can easy modify and refactore existing project with cut/copy/paste ANY object (from Method Argument to entire Project) within project and between ObjectBuilder projects. ObjectBuilder is not an IDE tool. It is portable two-way architect code-generation tool.
